Published: June 2003

Hoffman's Type 1 Screw Cover Wiring Trough, designed for indoor use, provides protection and a clear path for power and lighting control cables. It features a joining method that attaches end sections without fasteners or heat and is as strong as riveting or spot welding. The wiring trough is constructed of unpainted 16- or 14-gauge galvanized steel.
